The 2 in front of the x^2 can cause confusion. In this case, the equation can be divided through by 2, to produce x^2+2x-3=0. From here it can be factorised by working out what adds to make '2' and times ...

The acceleration or unbalanced force is proportional to the displacement of the object from its equilibrium position and acts in the opposite direction

Mathematically, this may be expressed as a=-...

Electric current is a measure of the rate of flow of charges. What this means is how many charges are flowing in a circuit in a certain time period. Mathematically this is expressed as I=Q/t where I is fo...

Firstly we would differentiate each equation with respect to t to find dx/dt and dy/dt- which gives us dx/dt=t and dy/dt=-4t^-2. Once you have found these you must divide dy/dt by dx/dt (or dy/dt x dt/dx)...

The first thing I would keep in mind when trying to categorise a text or a number of texts is that there are multiple different ways to categorise texts, but there has to be data in these texts to support...
